地震属性分析是以地震属性为载体提取地下隐含的地质信息,并结合地质钻井资料进行综合分析,将属性信息转换成与地下有关的信息进行预测。本文以安达工区为例探索属性在沉积相中的运用,首先对目的层位进行精细解释,然后确定时窗大小,以层间提取的方式提取地震属性,并动态分析了有效带宽以及其三维目标层沉积环境的变化。地震属性可以很好的辅助地质学科对沉积相进行分析。
Seismic attribute analysis uses seismic attribute as a carrier to extract hidden underground geological information, and combined with geological drilling data for comprehensive analysis, the attribute information is converted into information related to the underground to predict. In this paper, Anderson mining area is taken as an example to explore the application of attributes in sedimentary facies. Firstly, the target horizon is explained carefully, and then the size of time window is determined. The seismic attributes are extracted by inter-layer extraction, and the effective bandwidth and its three- Layer sedimentary environment changes. Seismic attributes can be a good auxiliary geological analysis of sedimentary facies.
